3/y =6/y-2<br>I need help on this please<br>worth 15 points

Leto [7]

Multiply both sides by y...

(3/y)y-(6/y)y-2y

Simplify it...

(3/y)y=3

(6/y)y=6

3=6-2y

Subtract 6 from both sides...

-2y=-3

Divide both sides by -2...

y=3/2

The solution is y=3/2

A town’s January high temperatures average 36 degrees (F) with a standard deviation of 10 degrees while in July the mean high

n200080 [17]

Answer:

55 degrees is more unusual in July as it is away from mean temperature as compared to January.

Step-by-step explanation:

We are given the following information in the question:

January:

Mean, μ = 36 degrees

Standard Deviation, σ = 10 degrees

July:

Mean, μ = 74 degrees

Standard Deviation, σ = 8 degrees

We calculate z scores corresponding to x = 55.

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

January:

$z_{score} = \displaystyle\frac{55-36}{10} = 1.9$

July:

$z_{score} = \displaystyle\frac{55-74}{8} = -2.375$

Thus, 55 degrees is more unusual in July as it is away from mean temperature as compared to January.
